Definitions
- joysticks Prior art joysticks assemblies, position controllers and the like (collectively “joysticks”) are widely used to control computers and machinery.
- Joysticks may use a variety of different sensor technologies, which may dictate the design of the joystick.
- a common type of joystick employs Hall-effect sensors and magnets.
- sensors and magnets In order to detect motion along the x- and y-axes, as well as intermediate axes, a plurality of sensors and magnets are typically required.
- the joystick design typically employs U-shaped arms operably connected to the joystick shaft. The arms or shaft are spring-loaded, and the joystick controller outputs signals based on the relative movement between the magnets and one or more of the sensors.
- the overall size must be increased to ensure sufficient spring leverage to pull the arms (and the joystick shaft) back to its center position.
- there is a need for a durable, high strength joystick assembly that is low profile and compact in size.
- a force sensing multi-axis gimbaled device includes a multi-axis movement assembly having an outer pivot plate having an opening, a middle pivot plate having an opening, the middle pivot plate pivotally received within the opening in the outer pivot plate, and an inner pivot plate that is pivotally received within the opening in the middle pivot plate.
- a biasing assembly is in communication with the multi-axis movement assembly, which is configured to impose a first force on the multi-axis movement assembly when the multi-axis movement assembly is pivoted about a first axis.
- the biasing assembly is configured to impose a second force on the multi-axis movement assembly when the multi-axis movement assembly is pivoted about a second axis substantially transverse to the first axis, and the biasing assembly configured to impose a third force on the multi-axis movement assembly when the multi-axis movement assembly is pivoted about a third axis.
- the force sensing multi-axis gimbaled device may further include a travel limiter assembly configured to limit the actuation magnitude of the multi-axis movement assembly.

- the inner pivot plate 58 also has a suitable thickness to define an exterior circumferential surface.
- First and second substantially coaxially aligned pivot pins 72 and 74 extend from opposing portions of the exterior circumferential surface of the inner pivot plate body 70 .
- the first and second pivot pins 72 and 74 are pivotally receivable within first and second substantially coaxially aligned pivot pin receptacles 76 and 78 defined within the middle pivot plate 62 to define the x-axis.
- the middle pivot plate 62 includes a middle pivot plate body 86 that is substantially similar in overall shape to the inner pivot plate body 70 , i.e., square with rounded corners.
- a center body opening 90 also similar in shape (i.e., square with rounded corners) is substantially concentrically defined in the middle pivot plate 62 for moveably receiving the inner pivot plate 58 therein.
- the middle pivot plate body 86 is of a suitable thickness to define an exterior circumferential surface and an interior circumferential surface within the center body opening 90 .

- the outer pivot plate 66 includes an outer pivot plate body defined by an upper body portion 100 and a lower body portion 102 .
- the upper body portion 100 is substantially similar in overall shape to the inner pivot plate body 70 and the middle body plate 62 , i.e., square with rounded corners.
- a center body opening 104 also similar in shape (i.e., square with rounded corners) is substantially concentrically defined in the upper body portion 100 for moveably receiving the middle pivot plate 62 therein.
- the upper body portion 100 may further include openings in each corner (not labeled) for mounting the gimbaled assembly 38 to a portion of a machine, assembly, etc., for which the force sensing multi-axis gimbaled device 30 is being used.

- the gimbaled assembly 38 is substantially low profile in design, or very thin in the “z” dimension. This is in contrast to many prior art joystick assemblies, which require a certain thickness in the “z” dimension for pivotal movement.
- the reduced “z” dimension thickness of the gimbaled assembly 38 does not require a reduction of the “x” and “y” dimensions.
- the gimbaled assembly 38 can be reduced in the “z” dimension without reducing the “x” and “y” dimensions.
- the aspect ratio between the “x” and “y” dimensions and the “z” dimension thickness of the gimbaled assembly 38 is small. As such, the gimbaled assembly 38 remains robust, and it of a size that is useable for many different systems.
- the gimbaled assembly 38 is also easily scalable in design.
- the inner, middle, and outer pivot plates 58 , 62 , and 66 are all substantially similar in shape and are substantially concentrically received within one another. As such, the size of each of the inner, middle, and outer pivot plates 58 , 62 , and 66 could be easily increased or decreased without affecting the compatibility of the pivot plates 58 , 62 , and 66 .
- the inner, middle, and outer pivot plates 58 , 62 , and 66 may be formed from any suitable method and material, they are preferably formed from injection molding. An injection molded part, as opposed to a part made from, for instance, machined components, can easily be made a different size. Thus, the gimbaled assembly 38 is easily adaptable for various design criteria.
- the inner, middle, and outer pivot plates 58 , 62 , and 66 may instead be pivotally secured together in another suitable manner without departing from the scope of the present disclosure.
- the pivot pins and pivot pin receptacles may instead be defined on the other of the inner, middle, and outer pivot plates 58 , 62 , and 66 .
- the first and second pivot pins 72 and 74 may instead be defined on the middle pivot plate 62
- the first and second pivot pin receptacles 76 and 78 may be defined on the inner pivot plate 58 . It can be appreciated that in such a configuration, the inner pivot plate 58 would still be able to pivot about the x-axis.
- the location of the pivot pins and the pivot pin receptacles may be oriented within the gimbaled assembly 38 in another suitable orientation, such as by shifting the location by ninety degrees (90°).
- 90° ninety degrees
- the combined pivotal movement of the middle pivot plate 62 about the y-axes and the inner pivot plate 58 about the x-axes enables the joystick shaft assembly 34 to effectively move about multiple axes through the gimbaled assembly 38 . More specifically, referring to FIG. 9 , the middle pivot plate 62 moves about the y-axes by pivoting within the outer pivot plate 66 , and the inner pivot plate 58 moves about the x-axes by pivoting within the middle pivot plate 62 and about the y-axes through the middle pivot plate 62 movement.

- the joystick pivot pin cup 138 includes an annular cup sidewall 140 surrounding a pivot pin contoured surface 142 defined on the bottom interior of the cup 138 .
- the annual cup sidewall 140 extends upwardly from the bottom interior surface of the center bottom portion 134 in a substantially transverse manner.
- the annual cup sidewall 140 is of a predetermined height to engage the joystick pivot pin 80 when the joystick assembly 34 moves in one or more axes of direction.
- the annual cup sidewall 140 defines an joystick pivot pin cup opening of a predetermined diameter to define the traveled arc length of the joystick assembly 34 . In that regard, the diameter of the joystick pivot pin cup opening is decreased to decrease the traveled arc length that the joystick assembly 34 , and the diameter is increased to increase the traveled arc length of the joystick assembly 34 .
- the contoured surface 142 of the joystick pivot pin cup 138 substantially corresponds to the arced movement of the joystick assembly 34 .
- the tip end of the joystick pivot pin 80 may be positioned to engage the contoured surface 142 such that the contoured surface 142 may help guide the joystick assembly 34 in its arced travel.

- the joystick pivot pin cup 138 may have an overall cross-shaped design to limit the movement of the joystick pivot pin 80 to the x- and y-axes.
- a key and paddle, or pin in slot design may be used. More specifically, the joystick pivot pin 80 could be moveably receivable within a slot defining a path of travel for the joystick pivot pin 80 .
- outer pivot plate 66 may be interchanged with another outer pivot plate having a joystick pivot pin cup 138 of a different configuration.
- the travel limiter assembly 40 may be modified as needed to increase or decrease the traveled arc length of the joystick shaft assembly 34 , or otherwise alter the path of travel of the joystick shaft assembly 34 .
- the pivot pin cup 138 could be defined within a travel limiter component separate from the outer pivot plate 66 .
- the outer pivot plate 66 could include only the upper body portion 100 , with the separate travel limiter component mateable therewith or otherwise positionable to interface with the joystick shaft assembly 34 .
- the separate travel limiter component could be easily interchanged to modify the travel limiter assembly as needed as needed to increase or decrease the traveled arc length of the joystick shaft assembly 34 , or otherwise alter the path of travel of the joystick shaft assembly 34 .
- the travel limiter assembly 40 is adaptable to meet the design criteria of the force sensing multi-axis gimbaled device 30 .
- the force sensing multi-axis gimbaled device 30 further includes a biasing assembly 42 that biases the movement of the joystick shaft assembly 34 along predefined axes and urges the joystick shaft assembly 34 toward its center position.
- the biasing assembly 42 is defined by first, second, third, and fourth leaf springs 146 , 148 , 150 , and 152 secured to and engageable with a portion of the gimbaled assembly 38 as it is moved into different positions.
- Each of the first, second, third, and fourth leaf springs 146 , 148 , 150 , and 152 includes a mounting piece portion 158 that is sized and configured to be mounted to a bottom surface of the middle pivot plate 62 .

- Each of the first, second, third, and fourth leaf springs 146 , 148 , 150 , and 152 further includes first and second tails 162 and 164 extending from the mounting piece portion 158 .
- the first and second tails 162 and 164 extend forwardly from the mounting piece portion 158 along substantially the same plane as the mounting piece portion 158 .
- the leaf springs are made from a suitable material, such as stainless steel, plastic, etc., so that the first and second tails 162 and 164 may moved into a deformed position relative to the mounting piece portion 158 , i.e., out of substantially coplanar alignment with the mounting piece portion 158 .
